Skip to main content Home Foundation and data collection Datadog Agent Software that runs resident on the servers and containers you monitor and delivers metrics, logs, and traces to Datadog. Integrations Integrations are the bundle of entry points that pour data from external systems such as AWS and MySQL into Datadog. Where you configure them splits into two families, the Agent side and the cloud account side, and which one you choose changes both what you can see and how billing is counted. Metrics From CPU utilization to user sign-ups, metrics are the core data of Datadog, recording every number in your environment as a time series. If you understand how they are counted before how they are collected, you avoid both aggregation mistakes and billing accidents. OpenTelemetry Support An explainer on the intake for feeding traces / metrics / logs from apps instrumented with OpenTelemetry straight into Datadog. There are 4 ways to receive the data, and which one you choose changes which Datadog features you can use. Tagging The backbone of Datadog: attaching key:value labels to metrics, logs, and traces so they can be filtered and aggregated across data types. As a feature it is unglamorous, but the quality of your tag conventions determines the usability of every screen afterward and the size of your bill.
